Video: Bank information theft bust

HACKENSACK, N.J. — In court Thursday, Orazio Lembo was described as the alleged ring leader of what police say was a massive scheme to steal 500,000 bank accounts and personal information, then sell it to bill collectors.

Lembo's alleged accomplices included branch managers and employees from some of New Jersey's biggest banks, including Bank of America, Wachovia and Commerce Bank.

All of them are accused of turning over customer bank account numbers and balance information for a profit of $10 per account. Even a state employee is accused of providing private information from state employment files.

"In some cases, the bank employees printed out entire customer computer screens and turned them over to Lembo," says Hackensack, N.J. chief of police Charles Zisa. "That information was then sold to his clients, which included more than 40 law firms and collection agencies."

Investigators say Orazio Lembo operated his company, DRL & Associates, out of his home, paying his accomplices tens of thousands of dollars over a four-year period, then allegedly re-selling that information for a profit of several million dollars to debt collectors and law firms.

Bank customers approached by NBC News couldn't believe it.

"It's horrible," says customer Adele Maldonado. "Not just for myself but for everyone else in town who banks here."

Security experts say the New Jersey case illustrates once again the vulnerability of private information, even when it’s supposed to be safe inside your bank.
